[adegenet-forum] Principal coordinate analysis

[Ana Rita Amaral]

Hi,

I am trying to do a PCA on microsatellite allelic frequencies from a genepop
file. I had no problem creating a geneind object.
I am also able to crate the table itself, which I have named obj.X, using
the command scaleGen(obj, center=TRUE, scale=TRUE, method="binom") but when
I try to do a PCA with that table, I get this error:

dudi.pca(obj.X, center=TRUE, scale=TRUe)
Error in dudi.pca(obj.X, center = TRUE, scale = TRUe) :
  na entries in table

I am not very familiar with R and this is beyond my comprehension! I think
there might be a problem in the table itself, but I cannot see where.
Any help would be appreciated,
Kind regards,

Ana Rita Amaral
